To dll whom 'it may coowem:

Be it known that I, Oscar Sonnen, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Pressing-Machines, of which the following is a speclcation.

M invention relates to pressing machines emp eyed by tailors for pressing the seams in garments, and my object is to provide a manually operated machine for the purpose, of strong and durable construction, capable of .being easily mani ulated and whereby a at pressure can e exerted with little c ort on the part of the operator.

In the accompanying drawings-Figure 1 is a view of :ny-improved machine showing the same in sectional side elevation in its normal osition, the view being taken at line 1, 2; Fi 2, a sectional elevation taken at ine 2, Fi 1, and showing the lever connections; ig. 3, a view similar to Fig. 1, but showing the parts in operative positionV with the presser-head in contact with the pressing-table or buck Fig. 4, a. plan view of the maphine with `the treadle broken away; Fig. 5, a broken view in rear elevation, takennt the lefthand side of the machine as presented in Fi 1; Fig. 6, an enlarged view in longitu inal section of 'the pressin '-table, taken at. line 6, Fi 1; 7, a. par ial plan and part sectiona view of the pressing-table, taken ut the irregularline 7, Fig. 6; Fig. 8, a transverse sectional elevation of the pressingtable taken at line 8, Fig. 6; Fig. 9, an enlarged view in longitudinal section through the presserhead, taken at line 9, Fig. f1; Fig. 10, a sectional elevation ofthe presserhead, taken at line 10, Fig. 9, and Flg. 11, a sectional View through the heater employed in connection withV the head, taken at line 11,Fig.9. f 'H A main frame l5, preferably of cast metal, is formed with two similar side-members 16, suitably spaced apartyto afford a housingr for lever mechanism hereinafter described'.

A bed 17 is secured on the frame, and leaves 1'8 are hinged theretol to form, when raised to the osition shown in Fig-4, extensions to the ta le, for supportingn garment being pressed. The body-portion of the machine comprises the frame, table and leaves, and

supports u pressing-table or buck 19 which is mounted on the table adjacent to its forward edge. The pressing-table is made preferably of cast metal, of hollow formation, and is provided with openings 20 at opposite sides and ends to permit of free circulation of air therethrough. A burner-tube 21 is attached at opposlte ends to the under side of the table 19, though spaced therefrom as shown in Fig. 6, and

gas is conducted thereto through a pipe 22 which forms a mixin -chalnber for the gas and air entering the atter through an injector 23 of ordinary form and construction. A cock 24 is connected with the injector and gas is supplied to the burner through a hoseor other {iexible connection 25 which leadsi rom any suitable source of gas-sup ly (no jshown), and is coupled to the coc 24. A ad 2G of asbestos or other suitable materia, of the desired thickness and density, and of a contour corresponding to that of the pressing-table, is placed upon the latter to insure only the requisite degree of heat at itsworkingY surface, and to prevent 'the goods bein pressed, from being scorched, as lwould resn t upon their contact with the table. The pad is held in pla'ce by a covering-cloth 27Mwhich projects at its edges beyond thepadfto afford a flap 28 which is secured in taut condition by an endless spiral-spring cable 29, stretched about the ressing-taLbe to clamp the flap, beneath a ange 30.

Guards 3l and 32 are provided respectivelyut the front und back of the pressing tuble '10 to prevent Contact with the ressing-tuble nt these points, of material lieing pressed. rlhe guard 31 s'preferubly hin ed to the buck along its upper edge so tlat w ien desired it muy be swung up by the operator to permit him to light the burner, or for the purpose of observing its condition or that of the fiume, and the guard 32 (Figs. 1 `and 4) muy be curved to correspond to the curve of the pressing=table and is rigidly secured in place.

. pressen-head 33 is provided to coperate with the pressing-table and is pivoted by' mcunsof a ball-and-socket joint 34, Fig. 9, to a vertically-disposed screw-shaft 35, equipped with it hand-wheel 36 for raising and lowering the head. The screw-shaft has ftween :ulti-friction rollers u threaded engagement with 'n sleeve 37 rigidly secured to one end of a longitudinally-sliding bar 38 forming an extensible resser-head `earrring-arm. The presserad is hollow an to iermit of circulation of airl through it. andl a heater 40 passes through an opening at one end and within the head is piroted at 4l. Gas is eondueted to the heater through a flexible tuhel' leading from any suitable souri-e of gus-.supply (not shown). and its flow is eontrolled h r a eoek 43. Fig. t'. The heater is aridi-shaped in cross-seetion as shown in Fig. ll` and a series of perforations -H 1is provided through the lower pull :nljaeent to eaeh lateral4 Aside. to direct the flames downward for heating the base. htm-hed to the head is the usual operatinghandle 45.

The har extends to the rear of the 1naehine and passes through a hollow swis'elin head -tt in wliieh ity is niovaliil)- cont-ined l|e- '47. one of whieh is loeated at the lower forward end thereof and the other at the upper rearward end. A hood or .shield 4S extends over the head and is attaeheri at its ends toV the har 38 und atl'ords a stop for limiting the movement of the har in either diret-tion. Two eollars 49 are forme-don the head and loosely.I surround a vertically-disposed shaft 50 about which it pivots 5 1 pinned to ,the Ishaft land interposed helt will he seen that the lmr .the head 4G and the shaft 50 form together a movable lframe for supporting a ndV @irri-ying: the presser-head.

tween the eollars 49.

t .itt the loiret-.ond of thejshaft und pinned to it is a collar provided with forwardly projw-ting ears 53. Fee. Figs. 1 and 2, to which are attaehed the. rearward ends of eompanion lin-ks 54 seem-ed at their opposite ends to the main frame 13. .Jisei-ond collar 5F is also pinned to the shaftelmt at a point HsliL'htlf below tlie" hed 17.' and two com-v panion links''t'v-are set-tired thereto 'at their rearward ends. at a Apoint back of thejsha'ftg' 'while their forward ends re pivote-,d vto ears 5i'` depending. from the filatnel. eollar .18 is adjustably mounted on the shaft 50. intermediate the collars 52 and '-55'. and held in -place b v a s'etscrew 59 shown h v dotted lines in Fig. I. Tito similar links (S0 are secured at their rear ends to this collar, y

at a ,point hack of the shaft. from which they extend forward. and Aati'ord between them. atetherir ends, a floating pivot 61 for'a 4treadle 65:.V Tlie treadle terminates .at its inner end in a head forming dronk-arm 63.

and is supported on the pivot 61 intermediate its ends. .t link 64 is piroted atits lower and between the ears 53 and its bifurcated upper end is secured to the lower end of the rork-arm. -while a'similar link G5 is pivoted at its upperend between tle earsy provided with holes 39 and to which' it.. is held` by u eollar A third 57 and its bifurcated lower end is secured to the upper end `o the rock-arm 63. The treadle extends forward :from its pivotal point into position convenient .to be actufted by the operator. and is normally maintained in a raised position by springs (iti. Vith the trendle in its normal or raised poi sition as shown in Fig. l. it hears against a hui'er (1T serured in the frame and when depres-eel lg): the foot of the operator to the position shown in Fig. strikes a lnxtl'er G1. 'lla-se hut'i'ers `whieh are Plefel'alllv formed of rubber `:erre tfM-uehion the treadle in its movements and to reliure the noise ineident to the operation of the tnaehi'ne. t i

By. referring to Fig. l it will he noted that the presser-head-33 is raised and out of Contact with the tahlelil and may be swung to one side as shown in Fig. l. lifter work to be pressed has been properly positioned upon the pressin table the presserdiead is swung back to tie proper position whereupon it is lowered into contat-l with the goods through the medium of the treadle and its operating parts. After thel release ofthe treadle' bv the operator. the springs G6 return it. and thepresser-hetnl to their raised positions. and the operation nia;- be continued as desired to press the garment at eaeh downward' movement of the parts.'

The links- 54. ofi and tttare all of the same length. and as the shaft. :'0 is moved it is eaused to travel in an upright litosition h v the links $4- and 5ft which suljiport tl'ieshaft` in suslnended eondition andy are disposed in parallel planes. 'To prevent any lateral moveiuentof the sha1' it is guided in its course by lugs T0 projetting: from the col lars and 55 into sliding contact with bearing: surfaces 71 on the inner .surfaces of the side rnenibers of tite main `frame.

It will he further'noted that the arrangement of the .rock-arm on the treadle which is piroted at 61. and the toggle-links (14 and 65 'positioned at theimgles shown in Fig. l. form afdouble orteompoui'id toggle so that comparatively at force may be exerted with the ex nditeureof but little pressure onthe tra e'.` 4 f In the o .ratiorl lof the machine, which will be readily understood from the foregoing detailed description. it is desirable to depress thetreadle to its limit of movement at eachtime it. is actuated, for thev purpose of bringing the toggles tol a dead center, and to'oom ate for the variation in thickness of pressed and to regulate the degree of pressure of the head thereon. the latter may be adjusted through the medium ofthe hand-wheel 36. After 'each pressin operation the springs 66 return `the tread e and its connecting mechanism to their nor mal position 'to raise the.pre.ssinghead from the garment after which theLhe/ad may be Il the lug "S thereon le P ,upper and lower swingin swung to one side out of the way, or the bar 38 carrying the same may be forced rearwardly for the same purpose.
